Welcome to Lacrosse Tens

Lacrosse has taken many forms over its long history, from its Indigenous origins on open fields with no fixed boundaries, to the modern game played today. As the sport has professionalized and gone international, the full field version — 10v10 — has increasingly become the format of choice at the highest level of competition. It's a shift that's still underway: men's field lacrosse has long been played 10v10, and in recent years, the women's game at the World Lacrosse and WLL level has moved to 10v10 as well.

We know the collegiate women's game is played 12v12, and that format has deep roots and a loyal following — this isn't about arguing that away. But it's worth noting that as women's lacrosse has grown at its highest levels — World Lacrosse, the WLL — the sport has moved toward 10v10. That's not a fringe experiment; it's a recent and deliberate shift at the top of the game, and we think it's worth paying attention to.

And it's not just team size. Even within men's lacrosse today, the game isn't fully unified — field dimensions, rules, and standards vary across levels and leagues. Lacrosse also includes other formats — sixes for the Olympics, box lacrosse, and other variations built for different rosters, venues, and audiences. We believe those formats can coexist alongside the full field game. Our focus here is simply unifying the full field version of the sport.

Lacrosse Tens exists to unify the full field game. Our goal is simple: bring the full field game to one standard — the same field dimensions, the same team size, 10v10 — across every level, men's and women's alike. This isn't about making men's and women's lacrosse identical; each game keeps the rules that make it its own. It's about giving both games the same field and the same format to build on, so the sport grows from a shared foundation instead of drifting further apart. We believe that shared standard will make the game stronger — easier to grow, easier to coach and officiate consistently, and better positioned to hold its ground as the sport's newer formats compete for players and attention. This is a place for players and fans who want the full field game unified, strengthened, and built to last.
